Hi,
Back in Jan you guys gave me some very helpful info on replacing a flat roof on a free-standing 6m x 3m garden room. Well, four months on I'm finally fixing the deck and hope to finish the whole thing this week...weather permitting.
Anyway, to provide the slope I used 50mm to 0mm firrings but now when I put a spirit level on the deck there are some areas where it appears to be dead flat. I'm naturally worried I'm going to get puddling in those areas. I'll be covering the roof in grit but I don't know whether that will help to reduce puddling (I suppose it will hide it if the water's not too deep!).
So any advice would be welcome...am I likely to get significant puddling and is there anything I can do about it at this stage...the only thing I can think of is to increase the slope by somehow jacking up the whole roof structure at the back edge.
Thanks in anticipation!
